Adis Medunjanin was questioned by the FBI in October 2009 about his alleged connections to Najibullah Zazi.
A man charged in a thwarted terror plot against the New York City subway system has pleaded not guilty.
Adis Medunjanin entered the plea to a superceding indictment Friday in federal court in Brooklyn.
He had previously pleaded not guilty to charges he sought to join two former high school classmates from Queens in what prosecutors called three "coordinated suicide bombing attacks" on Manhattan subway lines.
A revised indictment unsealed last month added new charges alleging a high-ranking al-Qaida operative named Adnan Shukrijumah had recruited Medunjanin, Najibullah Zazi and Zarein Ahmedzay in 2008 to receive training from the terror network in Pakistan. There was no mention of Shukrijumah at today's hearing.
Zazi and Ahmedzay have pleaded guilty and are awaiting sentencing. Outside court, Medunjanin's lawyer said he would not comment on Zazi, Shukrijumah or any evidence in relation to the case, saying only, "He is intent on proceeding to trial."
